To` all whom` t may concern:

Beit known that I, MICHAEL E. DALY, a citizen of `the United States,residing at Cincinnati in the county of Hamilton and State of hio, haveinvented certain new and useful Improvements in Latch Bolts, of whichthe following is a speciiication.

This invention relates to latch bolts such as are used upon doors forwashing machine cylinders and in many other places. The

. invention has particular relation to latches used on doors where thereis pressure `upon the bolt or where other factors cause wear of the boltand thereby prevent the door from being held solidly or tightly inplace. n prior constructions such wear has required renewal of theentire bolt.

The object of this invention is to provide a latch having a boltprovided with an ad-y justable and renewable toe, so that upon Wearacross the bolt toe it can be adjusted to take up the wear andultimately can be replaced with a new toe without discarding the entirebolt.

Further objects of the invention are in part obvious and in part willappear more in detail hereinafter.

Tn the drawings, which represent one suitable embodiment of theinvention, Fig. 1 is a plan view, illustrating a portion of a door withthe invention applied thereto; Fig. 2 is a perspective `view of thebolt; 'F ig. 3 is a side elevation thereof, illustrating a new positionof the toe after adjustment; Fig. 4; is a sectional elevation on theline Jr-4, Fig. 1; and Fig. 5 is a similar view on the line 5-5, Fig. 1.

1 indicates a portion of a door, such' as the hinged door of thecylinder of a washing machine, although it is to be understood that theinvention is notlimited to such use. Said door is provided with a framemember 2, one portion of which is provided with or formed as a latchcasing. In the construction shown member 2 is provided with an innerchamber 3 in which the bolt slides, and at one end of which chamber is ahollow extension 4.

e The bolt comprises a body portion 5 of rectangular form in plan view,said body portion having a recess or open space 6 at its center andbeing provided with a hol* low tubular rearward extension 7 in which isa pin 8. The body of the bolt slides in the chamber 3 and itscylindrical extension Said bolt is the compres 7 in the hollowextension4L.` normally pressed outwardly by sion spring 9, said outward inglimited by the screw abutment 10, which passes through a slot 11 of thebolt. Removal of screw 10 permits the bolt pin and spring to be whollywithdrawn from the latch chamber.

At its outer end the bolt is provided with a toe 12 having a straightface 13 engaging the latch keeper la in latched position, and the usualinclined face 15 whose engagement with the keeper pushes back the boltinto its cavity. This toe in struction is adjustable relative to thebolt body, for which purpose its rear face is provided with a series ofclosely spaced ribs or `teeth 16, extending and which interlock with andt a series of like teeth on the otherwise square end face on the bolt.The toe is held in position in any suitable manner, such as by a pair ofscrews 17 threaded into said toe and which extend through opening 18 inthe bolt. Access tothe screw heads may be had through openings 19 in theback of the bolt body.

Figs. 4land 5 illustrate the position of the parts when first assembled.The toe is solidly held to the bolt in its initial position. If wearoccurs the screw 10 is withdrawnand the bolt is taken out of its cavity.

y inserting a screw driver through the holes 19 the screws 17 may beloosened and the toe 12 raised to a new position, as shown in Fig. 3,which brings a renewed surface of the toe to the original position ofthe keeper engaging toe surface. The screws 17 c'an then be tightened upand the bolt restored to its cavity. This adjustment can be made fromtime to time to take upl wear and if the toe becomes too worn to befurther used it may be replaced by another toe.

lf the keeper engaging surface toe wearsv olf irregularly so thatadjustment of the toe to a new position interferes with rearwardmovement of the bolt into the latch cavity. the toe surface can be liledod flat or along a plane parallel tothe top surface of the .bolt so thatit slides back easily into the latch cavity.

`What l claim is 1. A latch having a bolt comprising a body portionhaving a transverse end face,

movement bethe present conlengthwise of the toe 3. A latch bolt,comprising a body portion having an open center providing transversefront and rear members, an adjustable toe on the front member, and aingv screw therefor having its head end extending toward the rear memberand accessible through an opening therein.

In testimony whereof I ailix my signature.
